To all whom t may concern.'

Be it known that I, HENRY STUEBNER, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Antifriction-Bearings, of which the following is a specification.

My invention relates more particularly to roller bearings and my leading object is to provide an improved construction adapted for self lubrication.

rlhe characteristic features of my invention are fully disclosed in the following description and the accompanying drawings in illustration thereof.

1n the drawings, Figure 1 is a longitudinal sectional view of a bearing embodying my invention; Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is a sectional view taken on the line 3-3 o1'n Fig. 1 with part broken away; Fig. 4 is a transverse sectional view taken through the center of a modified construction; Fig. 5 is a perspective view of a detached cage section used in the construction shown in Figs. 13; Fig. 6 is a perspective view of a second form of cage construction; Fig. 7 is a side elevation of a third form of cage construction; and Fig. 8 is an end elevation of the construction shown in Fig. 7.

1n the form of the invention illustrated in Figs. 1 to 3, casing sections 1 and 2 are provided with the interlocking longitudinal tongues 3 and grooves 4 forming irm joints holding in registration the complementary interior cylindrical surfaces 5 and 6, as also the circular raceways 7 and 8, and the circular channels 9 and 10, thereof. The section 2 has the cavities or subchannels 11 formed in the bottoms of the channels 10, with an aperture 12 leading therefrom through the sections, the apertures being closed by the screws 13.

Rollers 14 are provided with the intermediate circular raceways 15 which register with the raceways 7 and 8, and have the end journals 16 which register with the channels 9 and 10. Ring sections respectively comprising laminated circular plates 16, 17, and 18, I 1, are engaged in abutting relation in registration with the channels 9 and 10, the ends of the sections 16 extending beyond the ends of the `sections 17 towhich they 4, these rods 22 may have lubricate are attached and the ends of the sections 19 extending beyond the ends of the sections 18 to which they are attached to prevent relative lateral movement. lllhese ring sections are provided with radial slots 20 in the bottoms or inner ends of which the journals 16 are engaged, the slots forming of the outer and deeper plates 17 and 19 the wings 21 which run in the channels 9 and 10. Rods 22 have their ends fixed to the respective ring sections to unite them and form sectional cages. Balls 23, alternating with the rods, run in the raceways 7, 8 and 15, whereby the rollers are prevented from moving longitudinally. But, as illustrated in Fig. balls loosely sleeved thereon in registration with the raceways 7, 8 and 15. Sectional rings 24 are set in the outer ends of the members 1 and 2, and screws 25 may be passed there'- through into the respective sections 16, 17, and 18, 19, to hold the cage sections, balls and rollers in place in the casing sections whenthe latter are separated.

1t will be understood that, in operation, the channels 10 contain oil, which can be introduced through the capped apertures 26. rlhe sediment and dregs settle in the depressions 11, whence they can be drawn 0H" by removing the screws 13. As the cages revolve with the rollers and the balls, the wings 21 pick up oil in the channels 10 and the several parts of the bearing subject to wear.

As illustrated in Fig. 6, the cages are formed of ring sections 27 and 28 provided with., the radial channels 29 for engaging the journals 16 of rollers 14 and connected by rods 30. Wings 31, having their outer ends twisted, are fastened on the ends of the sections 27, against which the end-s ofv sections 28 abut, the wings overlapping the ends of sections 28 to prevent lateral movement of the cage sections.

As illustrated in Figs. 7 and 8, ring sections 32 and 33 are provided with interlocking ends'to prevent lateral movement, have the radial slots 34 for' holding the roller journals, are secured together by the rods 35, and have the wings 36, with twisted outer ends, Xed theretointermediate of their ends. It will be understood that these wings, shown in Figs. 68, provide an inexpensive and efficient construction for picking up oil and lubricating the bearing.

In practice, I prefer to use a packing material 24 between the rings 24 to prevent the lubricating material from Working out of the ends of the casing.

Having described my invention, I claim: 1. In an antifriction bearing, a casing having an interior cylindrical bearing surface and end channels adapted for holding v oil, a set of bearing rollers, and a cage comprising rings connected by rods, said rings having slots extending to their peripheries for receiving the journals of said bearings and Wings extending beyond saidrollers for picking up oil from said channels to lubricate said bearings.

2. In an antifriction bearing, a casing having sections provided With complementary cylindrical surfaces and complementary end channels, complementary ring sections having radial slots therein, said rings having Wings extending beyond said rollers and revoluble in said channels, means for holding said ring` sections. in coperative relation, and rollers having journals revoluble in said slots.

3. In an anti-friction bearing, a casing having sections provided With complementary interior cylindrical surfaces and complementary end channels, a cage comprising ring sections engaging in abutting relation, androds for holding corresponding ring sections together, and rollers having journals revoluble in said ring sections, said rings having slots therein forming Wings Which extend beyond said rollers into said channels.

4. In an anti-friction bearing, a casing having complementary sections provided with interlocking longitudinal grooves and channels, complementar` cylindrical surfaces, and complementary end channels provided With drainage means, in combination with a cage having complementary ring sections engaging inv abutting relation, .angularly disposedv Wings on said ring sections revoluble in said channels, and rollers journaled in said ring sections and revoluble on said cylindrical surfaces.

5. In an anti-friction bearing, a casing having complementary sections provided with interlocking members, complementary cylindrical surfaces having racevvays therein, and complementary end channels having means for collecting and draining sediment, rollers having races registering with said racevvays first named, balls movable in said raceways, and cages comprising ring sections having radial slots` in which sala rollers are journaled, and rods vfor holding said.

ring sections together, said ring sections having abutting ends whereby said cages are interlocked to prevent lateral movement and Wings revoluble i'n saidchannels.

In testimony whereof I have hereunto set my name this 15th day of May, 1914, in the presence of the subscribing Witnesses.
